Thanks. The car runs in modified production class (as set by the MSA) and therefore the engine block must remain the same type as standard, but modifications to it are free, as are cylinder head and induction. CC can increase, my brothers SS1 runs a 1900 CVH, but some clubs like to run a 1401-2000cc class, whilst others run a 1401-1800cc class, so I going over 1800cc risks getting put in an 1800cc + class with all the big stuff and turbo cars.

I also wanted to stay CVH for now as the majority of SS1's in competition are running nissan 1800 turbo (CA18 ET and DET) engines, and there was a bit of a stigma that there wasnt any point in competeing in the lower powered (and low HP potential) 1600 CVH, so I have got a bit of a point to prove for the under dog!

In the long run, I'm tempted to hang a turbo on the side of the CVH, but the first mission is to get it running on EFI.
